I have been working on setting up smart thermostats and smart AC control in my place. I have stumbled on a really hard problem, and I would really appreciate if you all would be so kind to offer me some guidance!
I have a Daikin cassette Air conditoner (daikin brc1c62) with a hard wired remote controller (pictured below). What this means is that the AC unit itself is controlled by this device that is mounted on the wall. The problem is when I removed this thermostat / remote controller, I realized there were only two wires connected to it, to poles P1 and P2 on the back of the controller.
I tried using a Go Control Zwave thermostat to replace it, but the problem is, regular smart thermostats use 4 or 5 wires.
I also have a Sensibo sky connected to a different split AC unit that works with an IR remote but there is no IR remote with the Daikin system to use with a Sensibo.
I also encountered this problem with another AC system (toshiba rbc-amt31e) that also uses this two wire system to connect the AC directly to a wall mounted remote controller.
Does anyone have any solution that I may use? Maybe there is some form of adapter or wiring?
I spoke to a Daikin rep and he told me that someone was able to connect their AC system similar to mine to a smart thermostat but he wasn’t entirely sure how.
Thanks for any help!
